[U-Boot] QSPI driver for Zynq and ZynqMP

[Siva Durga Prasad Paladugu]

Hi Jagan,

We would like to upstream quad and dual modes(parallel and stacked) support for qspi drivers of Zynq and ZynqMP. Can we send patches based on existing framework(drivers/spi , this is what we are using on Xilinx tree) or you want us to use any other?
I know we had discussion sometime back on this and we completed upstreaming driver without dual modes support as a first step. Please let me know on how to proceed further on adding quad and dual modes support. Any inputs are welcome.

Thanks,
Siva
